Solar PV Analysis of Kastrup, Denmark
The location at Kastrup, Capital Region, Denmark is not the most ideal for year-round solar energy production due to its placement in the Northern Temperate Zone. However, it can still generate a decent amount of electricity during certain times of the year. The best time to generate solar power at this location would be in summer when an average of 5.78 kWh/day per kW of installed solar can be expected. This drops significantly during autumn and winter with averages of 1.90 kWh/day and 0.83 kWh/day respectively, but rises again in spring with an average output of 4.54 kWh/day.
For a fixed panel installation at this location, tilting panels towards south by 46 degrees is considered optimal to maximize total year-round solar energy production.
As for local factors that could impede solar production, Denmark's long winters and short daylight hours could limit the effectiveness of solar panels especially during autumn and winter seasons. Also, Denmark's relatively flat topography does not offer many opportunities for placing panels at high altitudes where sunlight might be more direct and less obstructed.
However, these challenges can be mitigated through careful planning and design considerations when installing a PV system in Kastrup or similar locations:
1) Use tracking systems: These allow your panels to follow the sun across the sky which will increase their exposure to sunlight especially during shorter days.
2) Choose efficient panel types: Some types like monocrystalline silicon are more efficient than others in low light conditions.
3) Regular maintenance: Keeping your panels clean from dust or snow ensures they capture as much sunlight as possible.
4) Install additional capacity: Installing more capacity than you need during summer can compensate for lower power generation during other seasons.
In conclusion, while Kastrup may not have ideal conditions for constant high yield PV output throughout the year due to its geographical position and weather patterns; thoughtful planning, design considerations and regular maintenance can help to maximize the potential of solar energy production in this location.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 130 locations across Denmark. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Kastrup
Seasonal solar PV output for Latitude: 55.6204, Longitude: 12.5934 (Kastrup, Denmark), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 46° South in Kastrup, Denmark
To maximize your solar PV system's energy output in Kastrup, Denmark (Lat/Long 55.6204, 12.5934) throughout the year, you should tilt your panels at an angle of 46° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Kastrup, Denmark
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Kastrup, Denmark. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 46° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 39° South in Summer | 58° South in Autumn | 68° South in Winter | 47° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Kastrup, Denmark
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Kastrup, Denmark.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Kastrup, Denmark
Kastrup, Denmark is located in the eastern part of the island of Amager. The topography is relatively flat and low-lying, as it's typical for most parts of Denmark. It's situated near the coast, with the Øresund strait to its east.
For large-scale solar PV installations, areas with a high number of sunlight hours and minimal shading are ideal. Given that Denmark has a relatively flat terrain and moderate levels of sunshine compared to other European countries, there are several potential locations for solar PV around Kastrup.
1. Open fields: There are various open fields on Amager Island which could be suitable for large-scale solar installations.
2. Industrial areas: There are numerous industrial zones in nearby Copenhagen which could house rooftop solar panels or ground-mounted systems.
3. Near Airport: Copenhagen Airport is located in Kastrup itself, and airports often have extensive open spaces where solar panels can be installed without causing obstructions.
However, it’s important to note that while these areas might be physically suited for large-scale solar installations based on topography alone; factors such as local climate conditions (cloud cover), land use policies, environmental considerations (like impact on local wildlife), access to grid infrastructure and economic feasibility would also play a significant role in determining their suitability.
Denmark has been investing heavily in renewable energy sources including wind power due its geographical location providing ample wind resources; however this does not negate the potential for utilising solar PV where feasible.
Denmark solar PV Stats as a country
Denmark ranks 37th in the world for cumulative solar PV capacity, with 1,540 total MW's of solar PV installed. This means that 4.10% of Denmark's total energy as a country comes from solar PV (that's 19th in the world). Each year Denmark is generating 264 Watts from solar PV per capita (Denmark ranks 18th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Denmark?
Yes, there are several incentives for businesses wanting to install solar energy in Denmark. The Danish government offers a range of financial support and tax breaks for businesses that invest in renewable energy sources such as solar power. This includes grants, loans, and tax deductions. Additionally, the Danish Energy Agency provides subsidies for businesses that install solar panels on their premises. Finally, some local authorities offer additional incentives such as reduced electricity bills or free installation of solar panels.
